Hey Jeff, you experiences within the Dynavector line can be extrapolated to other cartridge lines as well.....and cable lines, amps, speakers, etc. The cost of diminishing returns hits fast and hard. It sounds as if you are facing a similar dilemma to when I changed from my VPI table/arm to a Basis table/arm. The Basis was much more transparent and revealing and Dynavectors weakness, a rather jagged higher end, is more exposed under such condition's. Dynavector's mate well with smoother sounding tables like the VPI.
The Benz line is a good reco, others that may also fill the bill would be a Koetsu, Shelter, Air Tight, Transfiguration, Sumiko or ZYX (silver). I haven't heard the Miyajima cartridges, so I cannot speak for them. You didn't mention a price range so I didn't mention specific models. I'm sure you can figure it out.
Cheers,
John
